Damascus and Moscow have accused militants and the White Helmets of staging several provocations involving chemical weapons to influence public opinion and justify foreign intervention in Syria.

Russia wants the White Helmets to be taken away from Syria as quickly as possible, Russian Ambassador to the United Nations Vassily Nebenzia said during a session of the UN Security Council on Wednesday.

"The White Helmets are a threat to security of regional states. Therefore, we would ask you, please, take them home as soon as possible. All of them," Nebenzia said.
